ATW28XXS Series
Connecting the inhibit input (Pin 2) to input common (Pin 10)
will cause the converter to shut down. It is recommended
that the inhibit pin be driven by an open collector device
capable of sinking at least 400A of current. The open cir-
cuit voltage of the inhibit input is 11.5 ±1 VDC.

Application Information
Inhibit Function
EMI Filter
An optional EMI filter (AFC461) will reduce the input ripple
current to levels below the limits imposed by MIL-STD-461
CEO3.
Device Synchronization
To take advantage of this capability, the system designer
must assign one of the converters as the master. Then,
by definition, the remaining converters become slaves
and will operate at the masters’ switching frequency.
The user should be aware that the synchronization sys-
tem is fail-safe; that is, the slaves will continue operating
should the master frequency be interrupted for any rea-
son. The layout must be such that the synchronization
output (pin 8) of the master device is connected to the
synchronization input (pin 8) of each slave device. It is
advisable to keep this run short to minimize the possibil-
ity of radiating the 250KHz switching frequency.
The appropriate parts must be ordered to utilize this fea-
ture. After selecting the converters required for the sys-
tem, a ‘MSTR’ suffix is added for the master converter
part number and a ‘SLV’ suffix is added for slave part
number. See Part Number section.
Typical Synchronization Connection
Remote Sense (ATW2805S only)
Better than 0.1% line and load regulation (case tempera-
ture constant) are typical when the remote sense leads are
used. If the remote sense leads are left unconnected, then
the output voltage (measured at pins 4 and 5) will rise to
approximately 5.4 VDC. If the remote sense leads are
shorted together, the output voltage may rise above 10 VDC
depending on load, possibly damaging both the converter
and load.
Whenever multiple DC/DC converters are utilized in a single
system, significant low frequency noise may be generated
due to the sight differences in the switching frequencies of
the converters (beat frequency noise). Because of the low
frequency nature of this noise (typically less than 10KHz), it
is difficult to filter out and may interfere with proper operation
of sensitive systems (communications, radar or telemetry).
Advanced Analog offers an option, which provides synchro-
nization of multiple AHE/ATW type converters, thus elimi-
nating this type of noise.
